Technical Abstract: Goldfield soft red winter wheat (Triticum aestivum L.) was developed by the Purdue University Agricultural Research Programs in cooperation with the USDA-ARS. It was released for its low incidence of Fusarium head blight (FHB), caused by Fusarium graminearum Schwabe, winterhardiness and moderate resistance to glume blotch, caused by Stagonospora nodorum (Berk.) and Septoria leaf blotch, caused by Septoria tritici Roberge in Desmaz., and very good soft wheat milling baking qualities. Goldfield has resistance to Hessian fly [Mayetiola destructor (Say)] biotypes B, D, and E (genes H5 and H6). Goldfield is named for its healthy bright straw at harvest, likely due to its resistance to leaf and glume blotches. Grain yield of Goldfield averaged 4,354 kg ha-1 compared to 4,560 kg ha-1 for Patterson, a current widely grown cultivar, at eight year location tests in Indiana under conditions of little or no FHB infection. Goldfield yielded 4,146 kg ha-1 compared to 3,858 kg ha-1 for Patterson averaged over five year-location tests in Indiana under moderate to high severity of FHB infection. Typically, the percentage of spikes of Goldfield that are diseased with FHB is one fifth that of Patterson, 5% for Goldfield compared to 26% for Patterson, averaged over eight year location tests in Indiana. The generation sequence of seed production for Goldfield is foundation and certified. Protection of Goldfield under the U. S. Plant Variety Protection Act has been applied for. Breeder seed of Goldfield is maintained by the Purdue University Agricultural Research Programs, West Lafayette, IN.
